China is warning users about so-called “backdoor security vulnerabilities” in Anthropic’s Claude code and asking users to uninstall it for security reasons.

• China’s National Vulnerability Database Warns Claude Code Contains Spyware
• Alibaba recently banned the use of Claude internally due to user tracking fears.
• Anthropic says it is designed to prevent model distillation and illegal use

China has accused Anthropic’s Claude code of containing what it describes as “backdoor security vulnerabilities” after the country’s National Vulnerability Database (CNVDB) found mechanisms capable of transmitting user information to Anthropic’s servers without the user’s explicit permission.

Researchers accuse the software company of collecting information such as user identity, geographic location, system environment information, and other machine metadata.
